I decided to give Rotella Express a try a short while ago, as it was 20 dollars for a tbn and everything else that I usually get. It's at a Kenworth dealer and I figured, what the heck. This is going to be a longer run (if everything is ok).
Amsoil AME 15W40

Here are the findings:
Al Cr Cu Fe Pb Sn Si K Na 57
Mo Water Ox 20.6
Vis 100 14.3
Glycol Neg
Fuel 2.2
TBN 11.1
Nit Soot 0.2
I started to have reservations when the woman behind the counter took my sample and turned her back to a small machine and started plugging numbers in....the above is what came out. I should have sent it to CAT SOS which is my usual...lessons learned. Always send to a reputable lab.
Here is the results from CAT that I got back today. Suffice to say, I am getting my money back from the Kenworth dealer.

Ox 783 (WHAT IS THAT?)
Nit 15

I probably won't be sampling for a while, but I'm curious as to the oxidation...never had a number that high before. Anyone have any ideas?
